Jupyterlab: Build Error

[dhirschfeld]

On my newly built container with jupyterlab 0.30.5, when I start jupyterlab it brings up the build dialog however the build fails and the dialog comes up again.

There are two suspicious entries in the output:

error An unexpected error occurred: "https://registry.yarnpkg.com/@jupyterlab%2fapplication:
self signed certificate in certificate chain".

and

$ webpack --define process.env.NODE_ENV="'production'"
'webpack' is not recognized as an internal or external command,

I haven't specifically installed webpack - just nodejs from conda-forge.

Any ideas how to resolve this?

...I also don't have yarn installed - is that a requirement now for building jupyterlab?

You don't need yarn, only node 4+. The issue there is the lack of a yarn.lock file to start. I see where the bug is and will put out a patch release.

Thanks for catching all our build system :bug: :bug:, @dhirschfeld!
